Oshkosh M-ATV
The Oshkosh M-ATV is a Mine-Resistant Ambush Protected (MRAP) vehicle developed by the Oshkosh Corporation for the MRAP All Terrain Vehicle (M-ATV) program. Intended to replace M1114 HMMWVs (Humvee), it is designed to provide the same levels of protection as the larger and heavier previous MRAPs, but with improved mobility.Tegler, Eric"Oshkosh M-ATV - Specialty File". ''Car and Driver magazine'', January 2010. History Requirements and selection In the summer of 2008, the U.S. Department of Defense (DoD) began to examine the possibility of developing and procuring a lighter-weight, all-terrain capable MRAP variant to address the poor roads and difficult terrain of Afghanistan. Source selection activity considered responses from more than 20 companies to a Request for Information (RFI)/market survey dated 21 August 2008 and in mid-November 2008 the U.S. government issued a pre-solicitation for an M-ATV. In early December 2008 the M-ATV formal Request for Proposals (RFP) was iss ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
M153 CROWS Mounted On A U
The Common Remotely Operated Weapon Station (CROWS) is a series of remote weapon stations used by the US military on its armored vehicles and ships. It allows weapon operators to engage targets without leaving the protection of their vehicle. The US military has fielded both the M101 CROWS and M153 CROWS II systems. System overview The CROWS system provides an operator with the ability to acquire and engage targets while inside a vehicle, protected by its armor. It is designed to mount on a variety of vehicle platforms and supports the Mk 19 grenade launcher, 12.7 mm M2 .50 Caliber Machine Gun, 7.62 mm M240B Machine Gun, and 5.56 mm M249 Squad Automatic Weapon. The system is composed of two parts: the mount which is fixed to the exterior of the vehicle and the control group. The mount is capable of 360° rotation and −20° to +60° elevation and is gyro-stabilized. The sight package includes a daylight video camera, a thermal camera and an eye-safe laser ran ...

Turbodiesel
The term turbo-diesel, also written as turbodiesel and turbo diesel, refers to any diesel engine equipped with a turbocharger. As with other engine types, turbocharging a diesel engine can significantly increase its efficiency and power output, especially when used in combination with an intercooler. Turbocharging of diesel engines began in the 1920s with large marine and stationary engines. Trucks became available with turbo-diesel engines in the mid-1950s, followed by passenger cars in the late 1970s. Since the 1990s, the compression ratio of turbo-diesel engines has been dropping. Principle Diesel engines are typically well suited to turbocharging due to two factors: * A "lean" air–fuel ratio, caused when the turbocharger supplies excess air into the engine, is not a problem for diesel engines, because the torque control is dependent on the mass of fuel that is injected into the combustion chamber (i.e. air-fuel ratio), rather than the quantity of the air-fuel mixture. ...
